The 36-year-old actress plays the story's villainous Queen Ravenna in the modern take on the Snow White fairytale, and she said that she dreaded having to deliver the story's most famous line, reported Contactmusic.
"I just dreaded it. We worked so hard to really find a foundation to ground the story emotionally in reality, and that was, for me, the only part that was kind of a throwback," Theron said.
"In a way it's like, 'My name is Bond, James Bond,' something that is so... How do you do that in a way that people aren't like, 'Meh?' And they decided to make me shoot that on my first day so I was just sweating bullets. I hated it, I hated it," she added.
The film also stars Chris Hemsworth as Eric the Huntsman and Kristen Stewart as Snow White.
